METALLIC TIE AND RAIL CLA MP THEREFOR.

Application filed April 3, 1928. Serial not 267,077.

The present invention relates to railroad ties, and has for itsprincipal ob ect to pro-' vide an article of this character constructedof metal and to provide means arranged thereon. for fastening the railin position upon the tie.

A further ob ect of the invention 18 to provide a hollow metallicrailroad tie adapted to support a pair of rails upon its upper face,

and forming the portion of the tie immediately beneath the rail of asolid construction, whereby to. increase the strength of the tie at thatportion subjected to the most strain.

A still further object is to provide an article of this character of asimple and practical construction, which is strong and durable, in whichthe weight of the tie is materially reduced, which is comparativelyinexpensive to manufacture, permits of the ready placing and removalofthe rail in position thereon,

and which is otherwise well adapted for the.

purposes for which the same is intended.

Other objects and advantages reside in the special construction andcombinationof the various elements comprising thev invention, referencebeing had to the accompanying drawings, forming a part thereof, wherein:

Figure 1 is a top plan view of a tie,con-e strncted in accordance withmy invention and showing a. pair'of rails secured in positiontl'iereupon. I

Figure 2 is a side elevat-ionalviewthereof.

Figure 3 is a longitudinal sectional view,

taken substantially along the line -3--3 of Figure-1. Y 7

Figure 1 is. a vertical sectional View, taken. along the line 4-4 ofFigure 2. r

Figure?) is a similar view, taken along the line 55 of Figure 3, and

Figure 6 is a perspective viewof one of the rail clamping plates.

Referring now to the drawing in detail, the invention comprises arailroad tie, constructed of metal and of a hollow formation. 'A pair ofrails 5 are adapted to seat upon the top 6, of the tie, adjacent theends thereof,

i the outer flange 7 of each of the rails'being engaged by upwardly andinwardly inclined lugs 8, cast integrally withthe tie and formed at theside edges of the'top portion 6-tl1ereof.

The center portion ofthe t-ie, between the! rails 5 has its top portionopen, as shown at 9, andwith the sides 10 adjacent such openedportions,'reduced in height as is shown atll.

The inner flange 12 of each of the rails 5 is engaged by a fiangededge13, formed on a retaining plate 14, adapted to seat upon the top portionGot the tie, along the edge of the opening 9., formed in the top and ateach end thereof. The plates lat and the top portion 6 of the .tie areprovidedwith aligned openings 15, through which bolts 16, may beinserted for securing the plates in a fixed position upon the tie, so asto secure the rail against movement thereon. v

The portion of the tie immediately beneath the rails 5 is constructed ina solid formation as shown. at'l'i', whereby to provide a reinforcedfoundation for the rails. In this manner, suliicient strength isprovided for bear ing the weight of the train as the same passes overthe rails and at the same time permitof considerable economy inthe'construction. of

' the tie, which otherwiseis of a hollow form-arails upon its uppersurface and with thetupper portion of the tie between the rails open,said the being of a solidconstructlon at the portion thereofimmediately, beneath the rails, a pair of rail flange engaging lugsformed integrally with the tie and adapted to engage the outer flange ofeach of said rails, a railattaching plate engaging the inner flange ofeach of said rails, and bolts upwardly through the portion of the uppersurface of the tie, adj acent the solid construction thereofforvsecuring the plates in, position, said tie having .its side wallsbet-ween the rails I reduced whereby to afford access to said bolts forWorking the bolts of therail from a position between the rails.

In testimony whereof I aflix my signature.

JOHN L. CARTMELL,
